Capacitance Measurement - Bahco BDACM1000 Manual De Usuario

• The resistance function can produce enough voltage to forward-bias silicon
diode or transistor junctions, causing them to conduct. To avoid this, do not
use the 40MΩ range for in-circuit resistance measurements.
• On 40MΩ range, the meter may take a few seconds to stabilize reading. This
is normal for high resistance measuring.
• When the input is not connected, i.e. at open circuit, the figure " " will be
displayed for the overrange condition.

3.2.4 Capacitance measurement

To avoid electrical shock and/or damage to the instrument, disconnect
circuit power and discharge all high-voltage capacitors before measuring
capacitance. Use the DC voltage function to confirm that the capacitor is
discharged.
The Meter's capacitance ranges are 4.000nF, 40.00nF, 400.0nF, 4.000µF,
40.00µF, 400.0µF and 4.000mF.
To measure capacitance (set up the Meter as shown in Figure 3-5):
1. Set the rotary switch to
2. Press the FUNC. key to select capacitance Test.
3. Connect the black and red test leads to the COM and
respectively (or you can use capacitor test lead).
4. Connect the test leads to the capacitor being measured and read the
displayed value.
Some tips for measuring capacitance:
• The meter may take a few seconds (>20 seconds on 400.0uF range) to
stabilize reading. This is normal for high capacitance measuring.
• To improve the accuracy of measurements less than 4nF, subtract the
residual capacitance of the Meter and leads.
• Below 100pF, the accuracy of measurements is unspecified.
